IP APER FOLDING AND DELIVERY MECHANISM.

Specification of Letters Patent. Patented Step1]. 19, 1911.

Application filed March 28, 1911. Serial No. 617,471.

To all whom it may concern: Be it known that l, ORLANDO S. GAUCi-i, a citizen ofthe United States of America, residing at Shelby, in the county of Richland and State of Ohio, have invented certain new. and useful Improvements in Paper Folding and Delivery Mechanism, of'which the-following is a specification.

My invention relates to improvements in a paper folding and'delivery mechanism and auxiliary means arenot' employed; to probe readily vide means of stripping each fold of the Web from the cylinders and packing the pile in a compact fornr between packer arms from which any part or all removed without interfering with the operation of the machine; I attain these .and other objects by the mechanism hereinafter fully described and illustrated in the accompanying drawings in which: i

' Figure 1 is a front elevation of a folding mechanism showing my improvement applied theretor Fig. 2 is a vertical cross sectional elevation of the device in line a-b of Fig. 1; showing the stripper fingers and jaws in one position. Fig. 3 is a vertical cross sectional elevation of the device showmg the stripper finger and aws 111 the opposlte position.

Referring more specifically to the drawings, reference numerals 1 and 2rcpresent the housings of the frame, in'which are suitably journaled the shafts 3 and l on which are rigidly mounted the folding cylinders 5 and 6 of the well known tucker-blade and 'aw t 7 3e and which forms no wart of the present invention. It will be understood, of course, that these cylinders are made of such a size will produce the desired length of the folded web. The cylinders are driven in opposite directions at a high speed and are supplied ,with the web 7 by feed rolls 46 and 47 described hereinafter. A shaft 8 nected to the studs 22 er of the pile can preferably journaled in the housings 1 and 2 and suitably geared, or otherwise driven at the proper speed, extends throughthe housings and has disks 9 and 10 mounted and rigidly held in place upon the outer ends. The disks are provided with crank pins 9 and 10 and connecting rods 11 and v 12 are pivotally connected at their lower free ends to oscillating fulcrum levers 13 and 14:. The fulcrum levers are pivotally mounted on the fulcrums l5- and 16 provided on the housings. Link-bars 17 and 17 and 18 and 18 are provided, the linkbars 17 and 18 being pivotally connected to the studs 19 and 20 to which is rigidly attached the stripper finger-bar 21 and the link-bars 1'7 and 18 being similarly con- 23 to which the stripper finger-bar 2-4: is rigidly attached.

lhe stripper finger-bars 21 and 24 are slidably connected to the housings 1 and 2 by means of the guides 25 which may be of any desired construction and which bars have attached thereto and rigidly held in place thereon by any desired means, the

stripper fingers 26 and 27 preferably formed to correspond with the shape shown whichis adapted to engage the annular grooves 28 formed. in the peripheral surfaces of the folding cylinders; 5 and 6. Slots 29 and 30 are formed in the housings 1 and 2 to permit free reciprocating movement of the studs 19, 20, 22 and 23 which pass therethrough.

It will be seen that the rotating shaft 8 transmits an alternating reciprocating motion to the stripper fingers 26 and 27 through the medium of the crank system of levers,

connecting rods and links above described. It will be understood, of course, that the speed of the shaft 8 must be suitably timed to operate in conjunction with the folding cylinders and delivery mechanism.

The cross bars 31 and 32 are attached to the housings 1 and 2 and rigidly held in place by any ordinary means, as for instance the bolts 33 and 34:. The cross-bars have rigidly attached thereto by means of rivets 35, the packer arms 36 and 37 having their upper ends slightly converged as shown in Figs. 2 and 3, and being adapted to receive the alternate folds of the Web or sheets as they are stripped from the folding cylinders adjusted position by means of set screws 44.

The shafts 38 and 39 are suitably geared and timed to permit the bars 42 and 48 to alternately engage the web 7 and divert a suiiicient am ount of the web from its line of travel to provide for each fold preventing the folding mechanism on the cylinder. from gri pin thelweb and tearin it.

t wi be observed that t e parallel bars provide'auxiliary means whereby a re-de termined amount of web is drawn bac from between the cylinders or diverted from its;

line of travel to compensate for the amount the folds, thus obviating the strain that frequently breaks the web. As the shafts carrying the parallel bars revolve, the outer periphery of the bars alternately contact with the web forcing'it out of its regular path or line of travel to each side thereof,

' alternately takin the pre-determined amount of, the we thiinakethe fold. This s operation is repeated "every time a fold is made on either cylinder.

The ordinary feed rolls 46 and 47 are used, the shafts 48 and 49 bein suitably journaled in the housings 1 an 2. ,The feed rolls are driven atany speed proper to withdraw an equal amount of web for the purpose intended from the printing press.

. The operation of my improved device is as follows: The web 7 which is to be folded is drawn from a printing press or other source of supply and passes between the feed rolls 46 and 47 .where it is forced by the friction of the rollstoward the folding cylinders and between the shafts 88 and39 of "the auxiliary feeding means of the web where the bars '42 and 43 alternately divert the web out of its path'or line of travel at 'the proper time taking up the proper amount of the web fed from between the rolls 'to compensate for the amount used on the end of the tucker blade in makin' the fold. When the bar 42 releases the we (as "shown by Fig. 2), the tucker blade 45 in the-"folding-cylinder 5 will force the web in the lateral openin 50 of the cylinder 6 taking" up all the s ack web and under the spring held jaw 51 at which time the cam "roller 52'wh1ch is rigidly connected to the shaft 53 through the arm 54 will be released from the circular cam 55 allowing the jaw 51 to grip the fold of the web by the tension of web taken up by the blades in makingg of the spring 54* upon the shaft 53,. and hold same securely as the cylinder revolves about its axis to the position shown in Fig. 3, and the roller 52 again engages the cam 55 opening the jaw and releasing the fold which is then carried by the stri per finger 27 to the packer rods. It will b that as the operation is repeated alternately, the web will be folded in zig-zag form and packed between the acker arms and that s after a predetermine number of folds, regulated by the length of the packer arms 36, has been packed, they may be removed from the folder by the operator without inter rupting the operation of the folder.

What I claim is 1. In a folding and delivering mechanism for paper, the combination of a pair of folding cylinders of the spring jaw and tucker blade type with an auxiliary feeding means adapted to take up a suflicient amount of Web between its source of su ly and the folding cylinders to form a f dld, and reciprdcating means operated by a rocker arm mechanism to strip the web Irom the folding cylinders. as it is folded in zig-zag fashion.
